The theory of near-field electromagnetism has enabled us to explore structures in sub-wavelength scales and opens up new possibilities of imaging, sensing and characterisation of materials. In this talk, I will review our recent research activities related to nanoelectromagnetics applied to microwave frequencies and beyond. In particular, how novel electromagnetic modelling tools have been developed and applied for the development of device innovation.<\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #ff0000\"><strong>Prof. Alexander I. Nosich<\/strong><\/span><br \/>\nInstitute of Radio-Physics and Electronics<br \/>\nNational Academy of Sciences<br \/>\nKharkiv, Ukraine<\/p>\n<p><em><strong>Periodicity matters: ultrahigh-Q resonances on the grating modes of large arrays of subwavelength\u00a0<\/strong><\/em><em><strong>scatterers <\/strong><\/em><\/p>\n<p style=\"text-align: justify\">This talk reviews the nature and history of the discovery of extremely high-quality natural\u00a0modes existing on periodic arrays of many subwavelength scatterers. Thanks to these modes,\u00a0infinite and large arrays can be viewed as specific periodically structured open resonators. These\u00a0grating or lattice modes (GMs), like any other natural modes, give rise to the associated\u00a0resonances in electromagnetic-wave scattering and absorption. Their complex wavelengths are\u00a0always located very close to (but not exactly at) the well-known Rayleigh anomalies (RAs),\u00a0determined only by the period and the phase shift between adjacent elements. This circumstance\u00a0has long been a reason for their misinterpretation as RAs, especially in the measurements and\u00a0simulations using low-resolution methods. On the frequency scans of the reflectance or\u00a0transmittance, GM resonances usually develop as asymmetric Fano-shape double extrema. In the\u00a0microwave range, GM resonances can spoil the performance of large phased-array antennas\u00a0assembled on flat surfaces. In the optical range, GM resonances are found behind exotic\u00a0phenomena such as \u201canomalous\u201d transmission, reflection and absorption, giant Faraday, Kerr\u00a0and Kerker effects, etc., and also behind the principle of operation of Distributed Feedback\u00a0Lasers. If a grating is made of subwavelength-size noble metal elements, then collective GMs\u00a0exist together with better-known localized surface-plasmon modes on individual particles. Their\u00a0interplay can result in the effect of induced optical transparency. Thanks to high tunability and\u00a0considerably higher Q-factors, the GM resonances can potentially replace the plasmon-mode\u00a0resonances in the design of nanosensors, nanoantennas, and solar-cell nanoabsorbers.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>","protected":false},"excerpt":{"rendered":"<p>Tuesday, September 4th, 2018, 14:00-15:30 Dr. Francesco Bonaccorso Graphene Labs IIT Central Research Lab, Genova Solution processed 2D-materials for printed electronics Graphene and other 2D crystals are emerging as promising materials\u00a0to improve the performance of existing devices or enable new ones.\u00a0A key requirement for flexible and printed electronics is the development of industrial-scale, reliable, inexpensive production processes,\u00a0while providing a balance between ease of fabrication and final material quality.\u00a0Solution-processing\u00a0is a simple and cost-effective pathway to fabricate various 2D crystal-based (opto)electronic devices, presenting huge integration flexibility compared to conventional methods.
